It's ludicrous that an ex amateur player - who's only taken a recent interest in the Laws can see the error of the ref's ways....and no one on commentary teams even make reference......
The problem with a lot of rugby commentators is that they still want to be mates with the current players and refs. I understand that, as a sport community rugby is second to none, and that includes refs, and nobody wants to leave it*, but their job is to explain what is going. If requires that they criticise the ref or players bluntly so be it.
Perhaps we need a few more Geoffrey Boycotts commentating and upsetting a few apple carts? But then again ....it is nice to have that community with refs taking time out to appear on TV and explain stuff.**
*I say that as someone who's been in the Army and understands that mentality.
** On reflection, perhaps I prefer that they're mates and rugby doesn't go the way of the round ball game with constant blaming of refs and refs losing their authority
